Intel tech support told me to do the jumper->floppy method.
Takes about 5 minutes before the flashing starts. I was ready to give up on it, but it eventually started flashing.
The bad news is that it does not solve the problem. Unless BIOS is flashed improperly, the floppy flashing doesn't make any difference.
I posted a similar thread over at XtremeSystems
and someone there indicated the behavior similar to what I'm seeing.
FYI, my board revision is: D53350-505
Same deal here. SATA devices connected to Intel ports work OK.
SATA devices conntected to Marvell ports will cause system instability after resume.
